SWINGLETREE-HOOK.

Specification of Letters Patent.

Patented Dec. 8, 1908.

Application led February 8, 1908. Serial No. 415,234.

To all whom it may concern:

Be it known that I, BENJAMIN F. EMERY, a citizen of the United States ofAmerica, and resident of Thayer, Union county, Iowa, have invented a newand useful Swingletree- Hook, of which the following is a specilication.

The object of this invention is to provide improved means for securing acock-eye, toggle chain, trace end or other draft device to aswingletree.

My invention consists in the construction, arrangement and combinationof elements hereinafter set forth, pointed out in my claims andillustrated by the'accompanying drawing, in which- Figure 1 is a planillustrating one form of my device. Fig. 2 is an end elevation of thesame. Fig. 3 is a cross-section of the same on the indicated line 3 3 ofFig. l. Fig. 4 is an end elevation illustrating a modified form of mydevice. Fig. 5 is a plan and Fig. 6 an end elevation illustrating afurther modified form of my device.

In the construction of the device as shown in Figs. 1, 2 and 3, thenumeral 10 designates a ferrule having a slight peripheral flange 11 onits outer end formed with a notch 12. An attenuated or apexed lug 13 isformed on the inner end portion of the ferrule 10 out of registrationwith the notch 12 and an attenuated or apexed lug 14 is formed on theperiphery of the ferrule 10 between and spaced apart from lug 13 andflange 11. A hook 15 is provided and formed with a ring 16 adapted tosurround the ferrule 10 and the opening of the ring 16 is formed with anextension 17 radially thereof which adapts the hook to pass on to theferrule by the straddling of the lug 13 by the extension 17. Thereafterthe ring 16 is retained on the ferrule 10 by the lug 13 and flange 11.The ferrule 10 is adapted to be mounted on one end portion of aswingletree 18. When it is desired to attach a cock-eye, toggle chain ortrace end to the hook 15, said hook is moved out of the position shown,where it is confined between the lugs 13 and 14, circumferentiallyI ofthe ferrule until the lug 14 registers with the extension 17, and thensaid ring and hook are moved outwardly so that the extremity of the hookpasses through the notch 12 and can receive engagement of the cock-eye.The cock-eye is mounted on the hook 15 and the said hook is turnedcircumferentially and moved along the ferrule until the extremity of thehook passes through the notch l2 and the extension 17 passes over thelug 14, and thereafter the hook is moved forwardly into the positionshown. When draft is applied to the hook 15 by the trace attachedthereto, said hook assumes the position shown in Fig. l, but when thetrace is slackened, the hook assumes the position shown in Fig. 2. Ineither event the ring 16 of the hook is confined normally between thelugs 13 and 14 when in use and between the lug 14 and flange 11 when thetrace is detached, until in the former position the trace can not beaccidentally detached from the hook.

In the construction of the device shown in Fig. 4, the flange 11 isomitted and a plurality of points or radial lugs 11a are substituted forthe flange. The lugs 11a perform the same function as the flange inretaining the ring 16a on the ferrule 10a and a lug, identical with 14,but not shown, conlines the ring when in use.

In the construction of the device as shown in Figs. 5 and 6, a cylinder10b is employed and is formed with an integral stem 19 threaded on itsexterior end and adapted to be screwed into a bore in one end of aswingletree 18a. The cylinder 10", of less diameter than the extremityof the swingletree and therefore the end of the swingletree performs thesame function in this con struction as the lug performs in theconstruction above described. In the construction shown in Figs. 5 and 6a lug 14a is emn ployed to confine the ring 16b of the hook 15b inproximity to the end of the swingletree when in use, and this lugregisters with a notch 12a in a flange 11b formed on andcircumferentially of the outer end of the cylinder. The manner ofattaching and detaching a trace, toggle chain or cock-eye manuallyrelative to the device shown in Figs. 5 and 6 is the same as thatdescribed in connection with Figs. 1, 2 and 3.

I claim as my invention- 1. A swingletree hook, comprising a supportingdevice, retaining means at each end of said supporting device, a radiallug on said supporting device between the retainin g means, a ringmounted on said support ing device and adapted for adjustment betweensaidv lugand. either of the end i'eextension adapted t0 passovereither.v of said taining means and' a= hook formed 0n said lugs attimes, and a hook 0n said ring, 10 ring.
